Set in a whimsical yet eerie world of personality heart-swapping, players assume the role of a heartless protagonist who must recover their misplaced heart before a surreal nighttime festival begins. As they navigate through bizarre interactions with eccentric characters who each claim to be the true owner of their heart, players will engage in clever dialogue choices that mix humor, ethics, and moral dilemmas. Each interaction reveals secrets about the protagonist's pre-heart life and challenges players to confront their own identity while unraveling the mystery of who truly deserves the heart. The game’s unique mechanic allows the player to 'heart swap' with characters, each providing different abilities and perspectives, complicating their quest with unpredictable outcomes and side-splitting scenarios.
